STM32U0 is the first Cortex-M0+ with a static consumption of only 160 nA in standby mode with RTC (Real-Time Clock) and 16 nA in shutdown. It also achieves 118 points in CoreMark and targets SESIP level 3 and PSA level 1 focusing on firmware code pro...
The new STM32H7R/S lines are built on the success of the STM32H7 series, offering even higher performance and security at a lower cost. The STM32H7R/S is a bootflash-based MCU powered by a Cortex®-M7 core running up to 600 MHz, with 64 KB of user fla...
Hello!I have problem with spi4 clock speed. I want to drive a lcd tft display but spi clock is max 500Khz, baudrate prescaler set to SPI_BAUDRATEPRESCALER_2. Is very weird. Initial setup was made with CubeMX to 48Mbit/s. APB2 clock is set to 96Mhz. I...
I am trying to read/ write data into FMC SDRAM (16 bit) in Bank 1. While writing the data hard fault occurred. What is the reason for that hard fault, is there any problem with data alignment, If yes what is the solution for it ?
This :double num= 10.85int written = sprintf(num_buf, "%1.17g", num);works in F4 using -u _printf_float into linker commands settings. But does not work in H7.Any suggestions?
Hi guys,I'm using STM32LO and i try to implement a code who aquire data of a sensor every 10 second in a fix day in a week. The rest of the time, the ship is sleeping.I'm trying to do that interruption with RTC and i configure the RTC and program my ...
Hello, I'm working with a PCB based on STM32L451VC MCU and I have different problems with the ADC. I'm trying to measure an input channel using the HALs provided by the STM32CubeMX but I can't achieve it. The main problem is that the bit ADRDY from A...
I read in section 6.2.1 of the STM32F479 reference manual that this Pin will Output a 20us reset pulse during Watchdog and other internal events. I did not find any Output characteristics for NRST and the statement in section 6.2.1 was stated almost...
Hi,I'm attempting to pass a parameter for a conditional compile from the gcc command line to my application. I have two build makefiles, one for debug and one for release. We have some code that's only meant for the release build. So far, so good. If...
STM32G070 is *NOT* supposed to have DAC, UCPD etc., at least not "officially"?!
